Fallon dead-on (and funny) in impression of Mayor Castro

Those bright eyes, that cute nose and big infectious smile. Even the way they wear their hair is similar.

So, it’s only natural that Jimmy Fallon would lead his late show Wednesday night with a mock-up of the keynote speech by his doppelganger, San Antonio Mayor Julian Castro.

“I’ve seen that a lot of people out there on Twitter are saying I look like the Latino Jimmy Fallon,” Fallon as Castro said. “And I must say, I’m truly honored: He’s a sexy man, with a sexy, sexy face.”

The comedy material was clever, albeit predictable: Immigration problems in Arizona (“They don’t let me in there”) ; the trouble with twins (“I may not even be the real Julian right now, perhaps I’m Joaquin. I’m Just kidding, or am I?”); comparing the struggles of Julian’s grandmother Victoria in this country to “Modern Family’s” Sofia Vergara; Mitt Romney’s cluelessness when it comes to Hispanics, mistaking Castro for his pool man Manuel.

No matter; it was very funny, particularly since Fallon aced it — from the cadence of his speech, to his hand gestures to the same blue tie our mayor wore on his big night.

The obvious next step: Wouldn’t it be fun to see Julian, his real twin Joaquin and his Hollywood twin Fallon all sitting side by side on NBC’s “Late Night”? Now, that’s a photo op!

The Fallon send-up was only one of many tributes to our mayor following his rousing speech at the DNC.

He spent a big chunk early on in CBS’ coverage of the DNC Wednesday night, chewing the fat with fellow S.A. native Scott Pelley. Moreover, there was that fab screen time sitting next to Michelle Obama while President Clinton spoke.

One of my favorite pieces came from another San Antonio talent, ABC’s John Quinones, who delivered a “New Kid on the Block” story on “Nightline” following Castro’s speech. We even saw the two of them strolling along the San Antonio River. “The mayor and I grew up in the same neighborhood,” Quinones said.

And look where they both are now. It’s been a great several days for San Antonio’s best and brightest. . .and I can’t wait to see more, lots more.
